Despite the fact that Jupiter has been observed for decades from the ground, and in situ by spacecraft, we still do not know its bulk composition, nor do we understand its global atmospheric dynamics well.

The sensitivity upgrade to the Very Large Array (VLA), combined with novel data reduction techniques, has enabled us to produce detailed longitude-resolved maps of Jupiter's atmosphere below the visible cloud layers.

I will compare these (still embargoed) maps with visible-light amateur images, and present results from radiative transfer modeling. In addition to radio observations, we also investigate the planet's atmosphere using 5-micron spectroscopy, which provides information complementary to the radio data.
